            {
                left = false;
            }
            if (e.KeyCode == Keys.D)
            {
                right = false;
            }
            if (e.KeyCode == Keys.W)
            {
                up = false;
            }
            if (e.KeyCode == Keys.S)
            {
                down = false;
            }
        }
    }
}

我想让玩家在碰到敌人的左侧时停止移动，但我总是得到一个错误，并且它突出显示if (Player.IntersectsWith(Enemy.Left))和Can't convert int into System.Drawing.Rectangle有什么想法吗?我试着看看这是否有效

if (Player.IntersectsWith(Enemy)) 
{
    left = false; 
    right = false; 
    up = false; 
    down = false;
}

，当然它会保持播放器的位置

当发生碰撞时，我该如何阻止玩家朝某个方向移动?

您似乎想要一个特定的碰撞。

你应该试试:

if(Player.X + Player.Width >= Enemy.X && Player.X < Enemy.X)
{
    right = false;
}

这样你就可以检查玩家的右侧是否与敌人的左侧相交，并且玩家的左侧位置是否小于敌人的左侧位置(玩家在敌人的左侧)

你将不得不添加高度和碰撞的东西，使它，所以你可以通过敌人，但我认为你已经张贴它应该工作ok。

注意:代码是未经测试的，让我知道你如何。
